Abstract
The invention relates to an herbicide for a farmland, especially to a compound herbicide composition for a wheat field, and belongs to the technical field of pesticides. According to the technical scheme adopted in the invention, the compound herbicide composition for a wheat field is characterized in that it contains effective components of bensulfuron methyl, tribenuron-methyl and flucarbazone-sodium and the weight ratio of the effective components is 1-10:1-8:1-9. The invention has the following beneficial effects: the compound herbicide composition has wide weed control spectrum, can be used to control and remove weeds in the field, has high security for crops, contains low toxicity, is less toxic to crops, human and animals, can be safely control and remove weeds without damaging crops, and has a significant effect of controlling and removing weeds.
Description
Technical field
The present invention relates to farmland herbicide, particularly relate to a kind of Compositional herbicide for cornfield composition, belong to technical field of pesticide.
Background technology
Crops need be used a large amount of weed killer herbicide managements of weeds every year to reduce loss because the harm of weeds can cause crop yield to reduce for this reason.In recent years, the weeds harm in the wheat paddock is on the rise, and because weed killer herbicide excessively uses, makes weeds increasing to the resistance of agricultural chemicals, thereby cause weed control efficacy to reduce year by year.At present, the topmost weed killer herbicide kind of wheatland is the agent of tribenuron-methyl list, the agent of tribenuron-methyl list or the agent of flucarbazonesodium list, can not remove fully the weeds in the wheatland.Because it is surging grass system that tribenuron-methyl list agent use for years makes generation and other broad leaved weeds of each regional clearvers resistance gradated by original weak tendency grass system; Weed killer herbicide tribenuron-methyl commonly used can only be prevented and kill off broad leaved weed between wheatland, and grassy weed is not had preventive effect; Fenoxaprop can only be prevented and kill off grassy weed and broad leaved weed not had preventive effect; The weed killer herbicide kind that therefore, need have better herbicidal effect.
Summary of the invention
Technical problem to be solved by this invention is, to the deficiency that prior art exists, a kind of technical scheme of Compositional herbicide for cornfield composition is provided, and kills the grass spectrum with what enlarge cornfield herbicidal, reduces the medicament usage amount, alleviates the poisoning of medicament to wheat.
The technical scheme that the present invention adopts is; A kind of Compositional herbicide for cornfield composition; 3-[4,6-dimethoxypyridin-2-yl]-1-[2-methoxy methyl acyl group benzyl] sulfonylureas), (its chemical name is tribenuron-methyl: 2-[4-methoxyl group-6-methyl isophthalic acid it is characterized in that (its chemical name is: to contain active ingredient and be bensulfuron-methyl; 3; 5-triazine-2-base (methyl) carbamic acid amino-sulfonyl] methyl benzoate) and flucarbazonesodium (its chemical name is: 4, and 5-dihydro-3-methoxyl group-4-methyl-5-oxo-N-{ [2-(trifluoromethoxy) phenyl] sulphonyl }-1H-1,2; 4-triazole-1-formamide sodium salt), the weight ratio of active ingredient is a bensulfuron-methyl: tribenuron-methyl: flucarbazonesodium=1-10: 1-8: 1-9.
The weight ratio of said active ingredient is a bensulfuron-methyl: tribenuron-methyl: flucarbazonesodium=4: 2: 3.

(3) experimental result
Safety: the dispenser " Invest, Then Investigate ", chemicals treatment district wheat plant height, Ye Se and blank district basically identical show to supply reagent agent 81% bensulfuron-methyl tribenuron-methyl flucarbazonesodium wettable powder to wheat safety.
Herbicidal effect: result of the test is seen Table I
It is better to find out that from Table I 81% bensulfuron-methyl tribenuron-methyl flucarbazonesodium wettable powder is prevented and kill off wheat paddock weeds effect.After the dispenser 15 days; 81% bensulfuron-methyl tribenuron-methyl flucarbazonesodium wettable powder mu with 10,15, the 20g herbicidal effect is best; Weeds strain preventive effect is 91-98.5%, and the preventive effect (85.8%), 10% tribenuron-methyl wettable powder mu that is higher than contrast medicament 81% bensulfuron-methyl wettable powder consumption 15g/ mu is with the preventive effect (87.8%) of 20g/ mu and the 81% flucarbazonesodium water dispersible granules mu preventive effect (85.3%) with 20g/ mu.After the dispenser 30 days; 81% bensulfuron-methyl tribenuron-methyl flucarbazonesodium wettable powder herbicidal effect is better; Weeds strain preventive effect is 91.6-100%, and the fresh weight preventive effect is 92-100%, is superior to contrasting medicament 10% bensulfuron-methyl, 10% tribenuron-methyl wettable powder and 70% flucarbazonesodium water dispersible granules.Evidence: bensulfuron-methyl, tribenuron-methyl and flucarbazonesodium compound herbicide composition are more obvious than single agent herbicide effects; Active ingredient is that 81% o'clock compound herbicide composition effect is more excellent.
Prevent and kill off wheat paddock weeds field control effectiveness test two:
1, test is handled
(1) 60% bensulfuron-methyl tribenuron-methyl flucarbazonesodium wettable powder (1: 1: 1) 10g/ mu

(13) clear water contrast
13 processing are established in test, and 4 repetitions are handled sub-districts for totally 52,20 square metres of every processing sub-district areas, and district's group is arranged at random.(1)-(9) bensulfuron-methyl tribenuron-methyl flucarbazonesodium wettable powder (Shandong Binnong Technology Co., Ltd.'s production) is for supplying the reagent agent; But 10% bensulfuron-methyl wet-milling wettable powder, 10% tribenuron-methyl wettable powder and 70% flucarbazonesodium water dispersible granules are the contrast medicament, and establishing not dispenser spray clear water is blank.Convert 30 kilograms in water for every mu, adopt 552 third type sprayers (0.7mm aperture) even spraying.The field main weeds has: amur foxtail, chickweed, hard grass, wild oat, bromegrass, descurainia sophia (l.) webb ex prantl etc.
2, pilot project and method
(1) safety: after the dispenser, the situation of growing of investigation wheat is estimated and is supplied the safety of reagent agent to wheat.
(2) herbicidal effect: every sub-district is got 4 points at random, investigates 1/4 square metre at every, and each investigation in 30 days is once write down weeds kind and strain number respectively after the dispenser, calculates weeds strain preventive effect, and claims that it is bright careless heavy, calculates bright grass and weighs preventive effect.
(3) result of the test
Safety: the dispenser " Invest, Then Investigate ", chemicals treatment district wheat plant height, Ye Se and blank district basically identical show to supply reagent agent (1)-(9) bensulfuron-methyl tribenuron-methyl flucarbazonesodium wettable powder all to wheat safety.
Herbicidal effect: result of the test is seen Table II
Through examination data Table II; Bensulfuron-methyl, tribenuron-methyl and the flucarbazonesodium composition that can know 5%-90% are to the good preventive effect of annual common weed; To weeds strain preventive effect between 84-91%; Between 86.9%-93%, can effectively prevent and treat the wheat paddock weeds to weeds fresh weight preventive effect, guarantee that the whole growth phase of wheat does not receive weed encroachment.
Test examples explanation, at bensulfuron-methyl: tribenuron-methyl: flucarbazonesodium=1-10: 1-8: in the 1-9 scope, annual gramineae and the broad leaved weed common to wheat paddock all have good preventive effect.The bensulfuron-methyl of best proportioning of the present invention: tribenuron-methyl: flucarbazonesodium=4: 2: 3 pairs common annual gramineae of wheat paddock and broad leaved weed preventive effect are the most remarkable; Weeds strain preventive effect and fresh weight preventive effect are all more than 91%; Lasting period is more than one month, basic controlling the crop smothering of wheat whole growth phase.
This test proves that also the herbicidal effect of hygroscopicity pulvis is best, and active ingredient is that the weeding of 81% wetting powder is best.Herbicidal effect of the present invention is just chosen representational test and is proved, suffices to show that technique effect of the present invention, and summary of the invention has been carried out technical support.
